Description

本発明は、エンジン発電機に係り、詳しくは、エンジン及び発電機を制御するための操作盤と発電機からの電力を出力する出力端子盤とをケーシングの一側面に備えたエンジン発電機に関する。   The present invention relates to an engine generator, and more particularly to an engine generator including an operation panel for controlling the engine and the generator and an output terminal board for outputting electric power from the generator on one side surface of the casing.

一般的なエンジン発電機は、床台の上部に設けられたケーシングの内部に、発電機及び該発電機を駆動するエンジン、燃料タンク等の機器を収容するとともに、ケーシングの一側面に、エンジン及び発電機を制御するための操作盤と、発電機で発電した電力を外部に出力する複数の接続端子を備えた出力端子盤とを配置している。操作盤及び出力端子盤の取付構造として、図７に示すように、ケーシング５１の内部に収容した発電機５２の上方を跨ぐようにして架台５３を設置し、この架台５３の上面に操作盤５４を固着するとともに、架台５３の下面端部に出力端子盤５５を固着し、操作盤５４の前面に上部カバー５６を着脱可能に設け、該上部カバー５６の下方に、出力端子盤５５を外部に露出させる開口を備えた下部カバー５７を着脱可能に設けたものが知られている。（例えば、特許文献１参照。）。   A general engine generator accommodates a generator and an engine that drives the generator, a fuel tank, and the like in a casing provided at an upper portion of a floor base. An operation panel for controlling the generator and an output terminal board having a plurality of connection terminals for outputting the electric power generated by the generator to the outside are arranged. As shown in FIG. 7, as a mounting structure of the operation panel and the output terminal board, a pedestal 53 is installed so as to straddle the generator 52 housed in the casing 51, and the operation panel 54 is disposed on the upper surface of the pedestal 53. , And an output terminal board 55 is fixed to the lower end of the pedestal 53, and an upper cover 56 is detachably provided on the front surface of the operation panel 54. The output terminal board 55 is externally provided below the upper cover 56. There is known a detachable lower cover 57 having an opening to be exposed. (For example, refer to Patent Document 1).

しかし、上述の特許文献１のものでは、下部カバー５７を取り外すことで前記架台５３の下方に位置する発電機５２のメンテナンスを容易に行うことはできるが、操作盤５４や出力端子盤５５をケーシング５１に着脱する際の配線作業は、発電機５２を跨いでケーシング５１内を上下に区画するように設けられた架台５３が邪魔になり、特に、出力端子盤５５への配線５８は、架台５３の下方からしか作業ができず、作業者に大きな負担を与えていた。また、架台５３のために死角となる箇所も多いことから、点検などの作業性にも悪影響を与えていた。   However, in the above-mentioned Patent Document 1, it is possible to easily perform maintenance of the generator 52 positioned below the gantry 53 by removing the lower cover 57. However, the operation panel 54 and the output terminal board 55 are installed in the casing. The wiring work when attaching to and detaching from the 51 is obstructed by the pedestal 53 provided so as to divide the inside of the casing 51 vertically across the generator 52. In particular, the wiring 58 to the output terminal board 55 is laid out. It was possible to work only from below, placing a heavy burden on the workers. In addition, since there are many blind spots due to the gantry 53, workability such as inspection is adversely affected.

前記開口部１３ｅの下部側上部には、発電機１５で発電した電力を外部に出力する複数の接続端子２２ａやコンセント２２ｂを備えた出力端子盤２２が設けられている。出力端子盤２２は、前記上部側面パネル２３と同じ厚さの箱状に形成されており、出力端子盤２２の背面板２２ｃの両側縁部が前記前面板１３ａ及び前記背面板１３ｂの端部に止着されている。また、出力端子盤２２の前面には、接続端子２２ａやコンセント２２ｂを覆う開閉可能な蓋部材２２ｄが設けられており、該蓋部材２２ｄの下方には、接続端子２２ａやコンセント２２ｂに接続した電源ケーブルの引出口２２ｅが設けられている。   An output terminal board 22 having a plurality of connection terminals 22a for outputting the power generated by the generator 15 to the outside and an outlet 22b is provided at the upper part on the lower side of the opening 13e. The output terminal board 22 is formed in a box shape having the same thickness as the upper side panel 23, and both side edges of the back plate 22c of the output terminal board 22 are at the end portions of the front plate 13a and the back plate 13b. It is fastened. Further, an openable / closable lid member 22d that covers the connection terminal 22a and the outlet 22b is provided on the front surface of the output terminal board 22, and a power source connected to the connection terminal 22a and the outlet 22b is provided below the lid member 22d. A cable outlet 22e is provided.

さらに、前記開口部１３ｅの下部側には、出力端子盤２２の周囲を覆う下部側面パネル２５が設けられている。この下部側面パネル２５は、該下部側面パネル２５の両側縁部が前記前面板１３ａ及び前記背面板１３ｂの端部に止着され、下部側面パネル２５の下縁部が床台１２に密着し、下部側面パネル２５の上縁部が前記上部側面パネル２３の下縁部に密着するように配置されるもので、上部中央には、出力端子盤２２を外部に露出させるための開口２５ａが設けられている。   Further, a lower side panel 25 covering the periphery of the output terminal board 22 is provided on the lower side of the opening 13e. In the lower side panel 25, both side edges of the lower side panel 25 are fastened to the ends of the front plate 13a and the back plate 13b, and the lower edge of the lower side panel 25 is in close contact with the floor base 12, The lower side panel 25 is arranged so that the upper edge of the lower side panel 25 is in close contact with the lower edge of the upper side panel 23, and an opening 25a for exposing the output terminal board 22 to the outside is provided in the upper center. ing.

このように、ケーシング１３の発電機１５側の側面に開口部１３ｅを形成し、該開口部１３ｅの両側に位置する前面板１３ａ及び背面板１３ｂの端部に前記上部側面パネル２３、前記出力端子盤２２及び前記下部側面パネル２５の両側縁部をそれぞれ止着するとともに、上部側面パネル２３に前記操作盤２１を取り付け、これらで開口部１３ｅを覆うように形成したことにより、ケーシング１３の水密性や防音性能を損なわずに、操作盤２１及び出力端子盤２２を取り付けるための架台が不要となり、操作盤２１及び出力端子盤２２の裏側に発電機１５の部分から操作盤２１に至る大きな空間部を形成することができる。   Thus, the opening part 13e is formed in the side surface by the side of the generator 15 of the casing 13, and the said upper side panel 23 and the said output terminal are provided in the edge part of the front plate 13a and the back plate 13b which are located in the both sides of this opening part 13e. Both the side edge portions of the panel 22 and the lower side panel 25 are fixed, and the operation panel 21 is attached to the upper side panel 23 so as to cover the opening 13e. In addition, a base for attaching the operation panel 21 and the output terminal board 22 is not required without impairing the soundproofing performance, and a large space from the generator 15 to the operation panel 21 on the back side of the operation panel 21 and the output terminal board 22. Can be formed.

したがって、ケーシング１３内を上下に区画する従来の架台が存在しないため、発電機１５、エンジン１６、制御盤１８、操作盤２１、出力端子盤２２にそれぞれ接続される各種ケーブルの配線作業を、前記空間部を利用して行うことができる。特に、前記操作盤２１を含む上部側面パネル２３を取り外すことにより、出力端子盤２２の配線作業を開口部１３ｅの上部側から行うことができるので、架台の下側からの作業に比べて作業性を大幅に向上できる。また、架台が存在しないので死角となる部分もなくなり、点検などの作業性も向上し、配線作業だけでなく、各部の点検や修理も容易かつ確実に行うことができる。さらに、下部側面パネル２５を取り外すことにより、発電機１５の保守作業なども従来と同様に行うことができる。   Therefore, since there is no conventional frame that divides the inside of the casing 13 up and down, the wiring work of various cables connected to the generator 15, the engine 16, the control panel 18, the operation panel 21, and the output terminal panel 22 is performed as described above. This can be done using the space. In particular, by removing the upper side panel 23 including the operation panel 21, the wiring work of the output terminal board 22 can be performed from the upper side of the opening 13e. Can be greatly improved. In addition, since there is no gantry, there are no blind spots, the workability of inspection and the like is improved, and not only wiring work but also inspection and repair of each part can be performed easily and reliably. Furthermore, by removing the lower side panel 25, maintenance work of the generator 15 can be performed in the same manner as in the past.

なお、本形態例では、操作盤２１とは別体に形成された制御盤１８を、操作盤２１の裏側で前面板１３ａ及び背面板１３ｂの裏面間にあらかじめ取り付けた状態としているが、制御盤１８が操作盤２１と一体的に形成されている場合は、制御盤１８と操作盤２１とを一緒に前面板１３ａ及び背面板１３ｂの端部に取り付ければよい。   In the present embodiment, the control panel 18 formed separately from the operation panel 21 is attached in advance between the back surface of the front panel 13a and the back panel 13b on the back side of the operation panel 21, but the control panel When 18 is integrally formed with the operation panel 21, the control panel 18 and the operation panel 21 may be attached to the end portions of the front plate 13a and the back plate 13b together.

また、操作盤２１、出力端子盤２２、上部側面パネル２３、下部側面パネル２５を前面板１３ａや背面板１３ｂの端部に止着する位置や手段は任意であり、操作盤２１や出力端子盤２２の大きさ、重量などの条件に応じて適宜選択することができる。   The position and means for fixing the operation panel 21, the output terminal board 22, the upper side panel 23, and the lower side panel 25 to the end portions of the front plate 13a and the rear plate 13b are arbitrary. The size can be appropriately selected according to conditions such as size and weight.
